The specific embodiment
In the drawings, be a kind of air-inflation tyre 1 that comprises tread portion, pair of bead and pair of sidewalls 2 according to vehicle tyre 1 of the present invention.Marked region 4 is distributed on the sidewall 2 at least.Shown in Fig. 1 a, 1b and 1c, marked region 4 can be that (Fig. 1 a), a distinct area (Fig. 1 b) is as a discontinuous or independent sector (Fig. 1 c) of the arc area that is provided with around tire axle collar shape for an annular section that extends continuously around the tire axle.
Marked region 4 is jagged zones, shows at least one mark 5 by the discountinuity that utilizes zigzag fashion 3.In the present invention, the discontinuous part of zigzag fashion 3 refers to following three kinds of situations:
(1) the discontinuous part of phalanges saw roller seating space 6 only;
(2) only refer between sawtooth ditch 6 the discontinuous part of the sawtooth ridge 7 that forms; With
(3) the discontinuous part of the discontinuous partial sum sawtooth ridge 7 of sawtooth ditch 6.
In the zigzag fashion 3 of mark 5, sawtooth ditch 6 and sawtooth ridge 7 do not have sawtooth ditch (sawtooth ridge) with substantially the same direction straight-line extension on other direction.Therefore sawtooth ditch 6 and sawtooth ridge 7 are parallel to each other basically.
Though can locally change tooth pitch for multifarious consideration, the distance between tooth pitch P or sawtooth ditch 6 (sawtooth ridge 7) is constant preferably.
Fig. 2 represents one embodiment of the present invention, and wherein marked region 4 is the annular sections on the sidewall 2 that the tire axle extends continuously.This marked region 4 comprises the mark 5A that each constitutes by the discontinuous part of sawtooth ditch 6.In this example, all sawtooth ditches 6 in the marked region 4 and sawtooth ridge 7 tilt with a fixing angle θ with respect to tire footpath direction R.Therefore, as shown in Figure 3, be parallel to each other basically at regional area sawtooth ditch 6 and sawtooth ridge 7 around mark 5 (5A).Inclination angle [theta] with respect to tire footpath direction R is set in 0～45 degree, preferably spends to 30 degree (being about 20 degree in this example) from 10 approximately.Scope at the tooth pitch P of the 4a of the radial inner end place in ring-shaped mark zone 4 is set at 0.6～1.5mm.
As shown in Figure 4, the sawtooth ditch 6 in this example has triangular cross-sectional shape.Sawtooth ridge 7 also has leg-of-mutton shape of cross section, and its apex angle is 90 degree basically.Sawtooth ridge 7 has two side 7S, and it is flat and is inclined to about miter angle with respect to sidewall surfaces 2S.In this embodiment, the summit of sawtooth ridge 7 or top are highly identical with sidewall surfaces 2S.
As shown in Figure 5, wherein demonstrate and have the concrete sawtooth ditch 6 that the discontinuous part of sawtooth ditch is provided than shallow portion 9.What demonstrate mark 5A together has the identical degree of depth (hb) than shallow portion 9, its scope be sawtooth ditch 6 the degree of depth (ha) 30%～70%.Surface than shallow portion 9 is flat, and 7S contrasts with the side, and its surface is parallel with sidewall surfaces 2S.Than shallow portion 9 only with the corresponding position of mark shape on extend.Particularly, shown in Figure 5 being labeled as under the solid situation, extend through the appropriate section of mark than shallow portion 9.Be labeled as under the hollow situation, extending through the appropriate section of the outline line (the width that this outline line is certain) of mark than shallow portion 9 with regulation.
Among Fig. 2, alphabetic string " STUDLESS " and " 256/70R16 " are mark 5A, and situation promptly above-mentioned (1) when requiring lower visibility, is preferably used this mark 5A, because be lower than sawtooth ridge 7 than shallow portion 9 and can be hidden in the back of sawtooth ridge.
As shown in Figure 6, can disconnect sawtooth ridge 7 under high any the situation of visibility requiring at end than shallow portion 9.That is to say and have breaking part 10, no matter and be solid mark or hollow mark along marker edge than the sawtooth ridge 7 of the vicinity of shallow portion 9.Yet, being labeled as when hollow, it is identical with the width of outline line that uninterrupted length may become.This is not preferred.Therefore this method preferably is applied to solid mark rather than hollow mark.Therefore such mark 5C is above-mentioned situation (3).
Fig. 7 represents above-mentioned situation (2).In this example, mark 5B only represents by the discontinuous part of sawtooth ridge 7.As shown in Figure 8, the breaking part 10 of sawtooth ridge 7 is formed on the outline line of mark or passes outline line.Therefore, this method can be fit to be applied to hollow mark.Under particular case as shown in Figure 8, because mark is represented the letter " O " of an italic, so outline line is a two circle, breaking part is arranged to two circle shapes.Therefore each breaking part extends through the appropriate section of two circles or mark.
When marked region 4 comprises thisly during only at the mark shown in Fig. 7, the bottom of breaking part 10 preferably is in identical level attitude with the sidewall surfaces 2S shown in Fig. 9.That is to say that sawtooth ridge 7 protrudes from sidewall surfaces 2S.The height of sawtooth ridge 7 (ha) is preferably in scope 0.2～0.8mm.In this example, except the bottom of breaking part 10, the bottom 6b of sawtooth ditch 6 is in identical level attitude with sidewall surfaces 2S.Tooth pitch P is that constant and the tooth pitch at the radial inner end 4a place of marked region 4 are not more than 1.0mm.
Therefore, be decided by the visual angle, even also to appear at breaking part 10 place's sawtooth ridges 7 be continuous, so mark 7 almost disappears.
Requiring than three types of 5A above-mentioned, under the situation of the visibility that 5B and 5C are higher, may be with the mark 8 and mark 5A of another kind of type, 5B and 5C are used in combination.
In the example as shown in Figure 2, alphabetic string " DPNLGR " and " UOASPC " are this marks 8.As shown in figure 10, this mark 8 is to be protruding to the top that is higher than sawtooth ridge 7 by bossing 12 from serration 3 to form, and the shape of bossing 12 is identical with the shape of mark, no matter and it is solid mark or hollow mark.The end face of bossing 12 is preferably the plane parallel with sidewall surfaces, but is not zig-zag.
Because mark 8 protrudes from serration 3, itself and mark 5A, the visibility height that 5B compares with 5C.In addition, mark 5A, the visibility of 5B and 5C changes to a certain degree from almost nil with the different of visual angle.Therefore,, just can provide very wide variation to come expressive notation, make it stay very strong impression to the people by mark 8 and mark 5 are used in combination.Contrast with bossing 12, under the situation than shallow portion 9 and breaking part 10, the marked region of lower tire side wall has higher counter-bending fatigue and cracking behavior.Therefore, all be that the situation that the bossing 12 by as shown in figure 13 constitutes is compared with all marks, can improve the durability of lower tire side wall.And be difficult for dirty.
Among the embodiment that mentions in the above, as the basic structure of serration 3, if do not consider zigzag discontinuous part, the cross-sectional plane of each sawtooth ditch or sawtooth ridge does not change along its length direction.For the shape of cross section of sawtooth ridge or sawtooth ditch, preferably use as shown in Figure 4 equicrural triangle and isosceles trapezoid as shown in Figure 9.Yet, also can use other shapes as scalene, right-angled triangle and non-isosceles trapezoid.
In addition, in order to obtain higher visibility or, also can change the shape of cross section of sawtooth ridge and/or sawtooth ditch and do not depend on discontinuous part (3,10) for multifarious consideration.For example, under situation shown in Figure 9, each sawtooth ridge 7 has at least one breaking part 10, and each sawtooth ridge has along the fixing transverse cross-sectional shape of its length direction by its breaking part 10.That is to say that for a sawtooth ridge 7, the part 7i in the mark is identical shape of cross section with the outer part 7o of mark.Yet, shown in Figure 11 a and Figure 11 b, can change the cross sectional shape between the outer part 7o of interior part 7i of mark and mark.In Figure 11 a, interior and outer part 7i and 7o have the symmetrical section shape, in order to change the light reflection by breaking part 6, and a wherein gentle slope among the side surface 7S and another is vertical.In Figure 11 b, the section shape of outer sawtooth ridge 7o is an equicrural triangle (A), and the cross sectional shape of interior sawtooth ridge part 7i is to add one to be used for increasing the rectangle B2 of sawtooth ridge height (ha) below equicrural triangle (A).
In Figure 12, do not change the cross sectional shape between part 7i and the 7o, but changed the distribution density of zigzag fashion by the tooth pitch that partly increases sawtooth ridge 7.In this example, the density of inside part 7i is 1/2 of Outboard Sections 7o density.The change of this density can be for multifarious consideration.
In addition, for type mark 8 commonly used, preferably the top surface of bossing 12 is aforesaid planes.But if end face is a serration, this zigzag fashion serration best and above-mentioned 3 is different, and is different with zigzag fashion 3 in the structure of sawtooth ridge, size, tooth pitch, shape of cross section etc. at least.
For the degree of depth (hb) than shallow portion 9, as explained above, the degree of depth (hb) is essentially constant for each mark 5.That is to say that this degree of depth can change between different mark 5.In addition, following change also is fine.For example, cover under the situation of another mark 5, compare the part that is capped with the part that is not capped and to have the different degree of depth at a mark 5.In addition, also can between the part that is not capped of another mark 5 of the partial sum that is not capped of a mark 5, change the degree of depth in addition.Comprise fully under the situation of another mark that at a mark mark that can be comprised has the degree of depth more shallow than the mark that comprises this mark, vice versa.
